What Your Doctor Can Do for Side Effects

If you're bothered by side effects, your doctor can often help by changing:

How much medication you take. Sometimes side effects can be stopped or minimized by reducing the dose. Or, your doctor may lower the dose and then raise it again more slowly.

When you take the medication. You may be able to cope with drowsiness or insomnia, for instance, by taking your medication in the evening or first thing in the morning.

How you take the medication. Taking your medication in smaller doses several times a day rather than in one dose can help. Taking your medicine with food might eliminate side effects such as nausea.

The type of medication. A different medication may be able to stop your symptoms with fewer or less severe side effects.

Always talk with your doctor before making any changes in how you take your medications.
